Copy protection, etc.

[J Holtendehouzer]

I'm nearly finished with a database that I think might be marketable, so I
am looking for an overview of 1) copy protection and 2) how to securely
implement a trial period for use with a time limit. Any tips you may have
or suggestions of books or links would be greatly appreciated.

Dear friend

Copy protection: By opening the database it should search for a specific
file, somewhere in your HD. If not found then quit.

Trial period: Add a field (date) and by first opening the databases set the
current date. By then opening the database check whether some days have
elapsed.
